Struct PageObjectCtxMut 

pub struct PageObjectCtxMut<'doc> { /* private fields */ }

Mutable context for accessing page objects on a single page.

Obtained via EditDocument::page_objects_mut().

Provides both read and write access. Immutable methods delegate through an auto-reborrow so you can mix reads and writes without giving up the context.

Example

let mut ctx = doc.page_objects_mut(0);
ctx.insert_object(new_obj).unwrap();
ctx.remove_object(0).unwrap();

Implementations

impl<'doc> PageObjectCtxMut<'doc>

pub fn get_object(&self, index: usize) -> Result<Vec<u8>, EditError>

Returns a copy of the raw content bytes for the page object at index.

ADR-019 T2 alias for FPDFPage_GetObject.

pub fn count_objects(&self) -> Result<usize, EditError>

Returns the number of page objects on this page.

ADR-019 T2 alias for FPDFPage_CountObjects.

pub fn remove_object(&mut self, index: usize) -> Result<(), EditError>

Remove the page object at index from this page’s content stream.

ADR-019 T2 alias for FPDFPage_RemoveObject. Namespaced here to avoid collision with the FPDFAnnot_RemoveObject alias on EditDocument.

See also AnnotObjectCtxMut::remove_object() for the annotation side.

pub fn insert_object(&mut self, object: PageObject) -> Result<(), EditError>

Insert a page object into this page’s content stream.

ADR-019 T2 alias for FPDFPage_InsertObject.
